Naval Group's Seaquest S unmanned surface vehicle recently completed five weeks of operations for NATO's Operation 'Baltic Sentry' and Exercise 'REPMUS 25'. The Seaquest S operated effectively in Sea State 5 conditions in the Baltic Sea during Baltic Sentry, conducting intelligence, surveillance, and reconnaissance tests.

The USV can be rented from Naval Group, as utilized by Task Force X. Additionally, during the REPMUS exercise in Portugal in September 2025, the Seaquest S operated alongside the French Navy from both shore and the Loire-class support ship Seine. Development of the unmanned combat underwater vehicle (UCUV) extra-large unmanned underwater vehicle (XLUUV) continues.
